Mordecai is smart and a bit of a clean freak. Hates things bring out of order and thinks things logically and sometimes can be too literal. Scarily competent at what he's good at, but completely hopeless when it comes to interpersonal relationships, shows very little emotion, has trouble connecting with people, is profoundly obsessed with everything being in order. He is very analytical and gets very annoyed when others don’t see things the way he does. Tends to use advanced vocabulary.
